Facebook comments are a great way to optimize your site for social media and add a level of user-engagement to you site. Quality website comments can increase your website's credibility, as well as its traffic. This tutorial will teach you how to use Facebook's API Connect to integrate comment boxes on your website in a few simple steps, utilizing a little PHP and some elbow grease.

You'll need to set up an application for your PHP app to make the connection. This will give you the unique keys for your application that'll be used in setting up the commenting. By including a Facebook javascript file, all you'll need to do is output a special "fb" HTML tag with the right attributes and a meta tag or two to configure it with your application's keys.
